Specification of Letters Patent.

Patented Dec. 6, i921.

/ Application filed August 9, 1920. SeriaI'IIo. 402,083.

To-all whom it may concem."

Be it known that I, WI LIAM SEYMOUR, a. citizen of the United States,residing at Paterson, in the county of Pass'aio and State ofNew Jersehave invented certain new arid useful mprovements in Reinforced BuildingUnits, of which the following-is a specification.

The object of this inventionis to provide an improved reinforced plateformed of Iplastic material and adapted for. use inuilding walls,ceilings, roofing, the forming of boxes or other containers and the likepurposes where a strong and durable and 1 readily attached'unit of thisclass is desired.

- Another object is to provide an improved roof, ceiling, or other wallstructure composed of a series of plates attached to a suitable supportand all in the same plane but of the reinforced spaced from each otherand a plastic mass filled into the spaces between the plates. I

In the accompanying drawing,

Figure 1 is a perspective view of one form plate embodying. myinvention'; I

Fig. 2 shows fragments of the reinforcing parts before the plasticmaterial is applied thereto; u

Figs. 3 and 4 show modified forms-of the plate;

Fig. 5 shows a roof or other wall structure formed in accordance with myinvention; and y Figs. 6 and 7 show fragments, on a larger scale, ofwall-structures with two different forms of plates.

Referring, first to Figs. 1 and 4, a. is a stifi- ]OlI1tS between theconstituent ening or remforcing structure such as reticulated sheetmetal. The holes or openings 6 in this sheet are preferably formed bypunching so as to leave around each hole and at one side of the sheet aburc. Around this sheet a is a sheet metal frame having (in the exampleillustrated four) vertical walls d and four horizontal walls eall lyingin the same 1 plane and projecting outwardly from one margin of theendless band which the several I walls (2 virtually constitute, thewalls e, be-

ing in effect a flange of the band. The walls at .are preferablyreticulated, as at f. The sheet a rests on the ledge formed by an inwardhead 9 on each wall 05.

With the sheet a held resting in some way against the ledge 9. plasticmaterial it, such as plaster or cement, is applied to both sides .1 and2, or the: flanges m and I of the sli eetand so' as not'only to fill thethe frame. When the material hardens, the

product will be a slab which is reinforced throughout by the sheet andalso reinforced and protected marginally by the frame, the materialbeing locked to the band of the frame, which is in effect cast as anintegral part thereof, and affords at the ledge a seat or support forthe slab, and the two portions of the material on opposite sides of thesheet a being joined by numerous connections 2' (Figs. 3 and 4). 1

In Fig. 2 the bead g is an inward fold formed in each wall 03 midway itswidth. In Fig. 3 the ledge j is formed by ahead is which at the outsideof the band constitutes a groove Z, and the flange m (corresponding tothe flange e) is a continuation of the outer margin of the bead. Thereticulated sheet 11. (corresponding to sheet a.) rests on the ledge jand the plastic material his assembled with the sheet and framesubstantially the same as in Figs. 1 and 2.

In Fig. 4 the ledge for the reticulated sheet 2 (correspondin to sheeta) is formed by first folding inwar ly one edge-portion of the band 9 ofthe frame, as at r, and then shaping the margin of'said edge-portion sothat it will extend inwardly, as at 8 to produce the ledge. The plasticmaterial is in this case assembled with the sheet and frame the same asalready described.

It will be noted that the flange e in Figs. u in Figs. 3 and 4 become aconvenient means for attaching the plate in position. The flange may bemailed to the available support 1) for the plate, Fig. 3, or it may beformed with a old w, Fig. 4, to be interlocked with another such fold inthus:

In Fig. 6 the folded flanges of two adj oinsecuring the plate in place,

-ing reinforced plates are made to compose gins rebent and interlockedwith the rebent edges of the two reinforced plates.

As shown in Fig. 5 the space a that is left between the adjoining platesmay be filled in With plastic material 2; and if the plates aremarginally undercut, as b the grooves indicated at Z inFigs. 4 and theplastic mass filling the spaces between the plates will be held bondedtherein.

The band is indicated in Figs. 3 and 4: by the reference character 25;the material h of the plate is looked to the band in the same way as inFigs. 1 and 2, viz., by projecting into the pockets formed by itsopenings t.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is 1. A reinforced unit for thepurpose setforth including a plastic slab and a supporting band of sheet materialextending around and lying throughout substantially its wholelongitudinal extent in adhering contact with the slab marginally thereofand being inwardly deflected as to a relatively great part of itslongitudinal extent and forming outwardly a marginal undercut andinwardly an elongated ledge-support for the slab.

2. A reinforced unit for the purpose set forth including aninclosure-forming band of sheet material having an inward bend formedtherein as to a relatively great part of its longitudinal extent andthereby form- 1,s99,oss

face and a plastic slab formed in and mom.

pying the inclosure formed by and adhering marginally to the band, saidflange projecting laterally farther than any other part of the unit.

4. A reinforced unit for the purpose set forth including aninclosure-forming band of sheet material having a flange projectingoutwardly at an angle thereto whereby to attach the unit to a suitablesupporting surface and a plastic slab formed in and occupying theinclosure formed by and adhering marginally to the band, said flangeprojectinglaterally farther than any other part of the unit, and saidband having an exterior longitudinal groove forming an undercut.

In testimony whereof I affix my signature.

WILLIAM SEYMOUR.
